Brief Summary:
Scant data have been reported on the effects of weight self-monitoring during weight control. The purpose of this pilot project was to consider the questions: Is it possible to assign participants to engage in daily weight self-monitoring, and are there differential effects on mood of daily versus weekly weighing?

Condition or disease Intervention/treatment Phase
Weight Loss Body Weight Behavioral: weighing frequency instructions and tips Not Applicable

Detailed Description:
This study tested the feasibility of assigning participants to daily or weekly weighing, monitored adherence to weighing instructions, and tracked additional behavioral and psychosocial indicators over a period of six months. It was hypothesized that there would be no differences in mood or adherence between daily versus weekly weighing conditions. Knowledge about the benefits of frequent self-weighing may shape public health recommendations for regular weighing as a weight reduction or obesity prevention strategy.

Primary Outcome Measures :
  1. Adherence to Weight Tracking Instructions [ Time Frame: 6 months ]
    Participants were assigned to daily or weekly weight tracking, and were asked to return postcards once a week with weights recorded (7 for daily, 1 for weekly).


Secondary Outcome Measures :
  1. Changes in Depression Ratings [ Time Frame: baseline to 6 months ]
    Ratings of depressed mood, assessed by the Beck Depression Inventory, were obtained at baseline, three, and six months; the comparison of depression scores between groups and over time from baseline to 3 and 6 months was considered as a secondary outcome and analyzed using repeated measures multivariate analysis of variance (MANOVA). Scores on the inventory range from 0 to 63, with higher scores indicating greater presence of depressive symptoms. Scores from 0-10 represent normal mood; 11-16 = mild mood disturbance; 17-20 = borderline clinical depression; 21-30 = moderate depression; 31-40 = severe depression; > 40 = extreme depression.

  2. Changes in Anxiety [ Time Frame: baseline to 6 months ]
    Ratings of anxiety, assessed by the Beck Anxiety Inventory, were assessed at baseline, three, and six months; a comparison of anxiety scores between groups and over time from baseline to 3 and 6 months was considered a secondary outcome and analyzed using repeated measures MANOVA. Possible scores on the scale range from 0-63. Scores from 0-7 indicate minimal anxiety; 8-15 = mild anxiety; 16-25 = moderate anxiety; 26-63 = severe anxiety.

  3. Changes in Body Image [ Time Frame: baseline to 6 months ]
    Changes in self-reported body image were assessed at baseline, three, and six months using the Appearance subscale of the Multidimensional Body Image Questionnaire. The subscale has a range of 0 to 42, with higher scores indicating better body image. A comparison of body image scores between groups and over time from baseline to 3 and 6 months was considered a secondary outcome and analyzed using repeated measures MANOVA.

  4. Changes in Barriers to Weight Tracking [ Time Frame: baseline to 6 months ]
    Perceived barriers to self-weighing were assessed at baseline, three, and six months using a scale created for this study. The scale has a range of 18 to 90, with higher scores indicating greater perceptions of barriers to self-weighing. A comparison of barriers scores between groups and over time from baseline to 3 and 6 months was considered a secondary outcome and analyzed using repeated measures MANOVA.

  5. Changes in Perceptions of Weight Tracking [ Time Frame: three to six months ]
    Perceptions of weight tracking (ease of remembering and understanding, usefulness, awareness, interest, reward value, satisfaction, motivational value) were assessed at three and six months using a scale created for the study. The scale has a range of 0 to 64, with higher scores indicating greater perceptions of favorability of weight tracking. A comparison of perceptions scores between groups and over time from 3 and 6 months was considered a secondary outcome and analyzed using repeated measures MANOVA.
